ABSTRACT

Conclusion:

Although the findings of the acoustic analysis and perceptual voice evaluation results obtained in this study are generally consistent with the literature, the present study differs in that it compared four different partial surgical procedures with a versatile voice evaluation. Limitations to this study are not considering different reconstruction techniques and no subgroups equal in number.

Results:

According to the perceptual and acoustic analysis scores, the supraglottic laryngectomy subjects had the closest findings to the normal voice quality, whereas the supracricoid partial laryngectomy group was the most distant among surgery groups. There were no significant differences between the endolaryngeal laser surgery and vertical partial laryngectomy participants. The supraglottic compression parameter was found to be worse in supracricoid partial laryngectomy compared to supraglottic laryngectomy and endolaryngeal laser surgery.

Methods:

After receiving the patient history, evaluations were made, including perceptual analysis, videolaryngoscopic examination, and acoustic analysis. For all evaluations, the control group and the study group findings were compared.

Objective:

As a result of partial or total surgical removal of the larynx due to larynx cancer, there are several aspects of patient’s life that are altered, such as the anatomical, physiological, psychological, and social aspects. One of the key elements that affect the quality of life of postoperative patients in organ-preserving surgeries is the vocal function.

This study is designed as a prospective case-controlled study aimed at comparing the degree of dysphonia occurring after the implementation of different conservational laryngeal surgery types. The voice quality of the study group (n=49) consisting of the individuals who underwent endolaryngeal laser surgery, vertical partial laryngectomy, supraglottic laryngectomy, and supracricoid partial laryngectomy has been compared with the voice quality of healthy control group (n=20) individuals.
